Pattinson says dating Stewart has been 'traumatic'

Unlike their "Twilight" characters, Rob Pattinson and Kristen Stewart's love affair may not stand the test of time.

Pattinson tells the April issue of Vanity Fair that the attention surrounding his real-life romance with his onscreen love interest has put a strain on their relationship.

"It's just very traumatic," the 24-year-old Brit complains. "When this is over, the media will lose interest. There'll be nothing to say. It won't fit into a headline anymore. It won't fit into a template."

Even before their secretive romance began, Pattinson admits he was a fan of Stewart's body of work.

"Kristen is very focused on being an actress. I mean, that's what she is — she's an actress. Whereas I ... I just don't really know," the actor admits of his 20-year-old flame.

"She's cool. Even before I knew her I thought she was a really good actress. Like, I saw "Into the Wild," and I thought she was really good in that," he raves. "I still think there are very few girls in her class that are as good as she is."

His private life aside, Pattinson also admits to having an unlikely fondness for Charlie Sheen.

"I like crazy people who don't give a f***," he explains, adding that he's a fan of the 45-year-old actor's "little escapades."

"I never change the channel in my trailer. I just watch reruns of "House of Payne" and "Two and a Half Men." I love "Cops" — I think it's my favorite TV show," he laughs. "God, I sound like such a loser."

Not that anyone could blame Pattinson for wanting to stay out of the spotlight.

"There's nothing you can do about it. That's the way it is," Pattinson explains of the mega-fame "Twilight" thrust upon him. "But it is weird being part of that, kind of representing something you don't particularly like. God, I just really head-butted it."

"This thing with everyone knowing you, it's weird, because people have this one-sided relationship where they look at your picture and feel they know you more than someone they actually know," the actor continues. "I don't really know myself that well."
